'URNER SPECIFICATION forming part of Letters Patent No. 731,548, dated June 23, 1903.

Application iiled April 22, 1902 To @ZZ whom t may concern:

Be it known that we,'JOsEPH H. DIEHL and ISRAEL B. TAYLOR, citizens of the United States, residing at Buffalo, in the county of Erie, State of New York, have invented certain new and useful Improvements in Gas- Burners; and wedo hereby declare the follow-` ing to be la full, clear, and exact description of the invention, such as will enable others 1o skilled in the art to which it appertains to make and use the same.

Thisinvention relates to gas-burners in general, and more particularly to the class of iucandescent gas-burners wherein air is adx5 mixed with the gas in suitable quantity and is fed to a mantle, the gas being burned upon y the surface of the mantle to heat the latter to incandescence.

The object of the invention is to provide a 2o construction wherein the air and gas will be mixed thoroughly and in proper quantity before introduction into the mantle in the proportions of air andgas ture may be accurately determin z 5 the most efficient results.

in the mixed to secure A further object of the invention is to prol vide a durable structure that willinclude a minimum of parts and which will be simple and cheap of manufacture.

Other objects and advantages of the invention will be understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of 3 5 reference indicate similar parts in the several views, Figure 1 is a side elevation of the complete burner, the adj ustable damper being partly open. Fig. 2 is a vertical section taken centrally through the entire device.

ent device comprises a mixing-chamber including a body portion 5, which has substantially the shape of'an ellipsoid, the end portions thereof being arched, as shown, while the central or intermediate portion is cylindrical, and at the lower edge of this cylindrical portion is the ing iiange 6. the cylindrical continuous circumscrib- The body 5 is hollow, and in central portion thereof are and wherej Referring now to the drawings,.the pres-' semina'. 104,227.

formed openings 7, which are spaced preferably equidistant and which permit of access of air to the interior of the body.- To regulate `the inflow of air through the openings 7, it is only necessary to cover said openings partly, `and for this purpose an annular band or jacket is disposed upon the cylindrical portion of the body 5 andfrests with its lower edge upon the circumscribing flange 6. In the band or jacket, which is shown at 8, are openings 9, which correspond in location and size to the openings 7, and the band or jacket ts the body 5 with sufficient looseness to permit of rotation thereof, while its fit is sufciently snug to practically cut oft thepassage of air through the openings 7 when the band orja'cket is Vrotated to lie with its portions between'its openings over the openings of the body. With the openings of the body closed,as above described,ifthe band or jacket be rotated the openings 7 will be gradually uncovered until the openings of the body and band or jacket will be in full registration. Continued rotation of the band or jacket or reverse rotation thereof will act to gradually close the openings in the body. Thus by properly adj usting the band or jacket upon the body the proper feed of air into the body through the openings 7 may be determined.

From the lowerend of the body 5 projects a tubular extension 10, which is interiorly threaded and communicates with the interior of the body, and engaged with the threads of this tubular extension is the tubular nipple 11, which is screwed through the tubular extension, so that its inner discharge end lies well within the body, th e nipple being held in proper adjustment with its inner end in proper relation to the openings 7 by means of the set-screw 12. At the` lower orouter end of the nipple is an enlargedinteriorlythreaded portion 14, which is adapted to be screwed down onto the ordinary threaded end of the arm of a gas-bracket or chandelier, so that gas may pass from said arm into and through the nipple. To permit of theguse of the saine nipple in connection with different kinds and grades of gases and gases under dierent pressures, the nipple is provided with a tip 15, which is forced down into the end of the nipple and is in the form of a thimble or ferrule, the upper end of which is perforated with one or more holes of proper size to get the most efficient results with the diiferent gases with which the burner may be used. As an additional means for permitting access of air to the body 5 openings 16 are formed in the bottom of the body, one at each side of the tubular extension thereof. At the upper end of the body 5 is a tubu lar extension 17 of greater diameter and of greater length than the extension at the lower end of the body, and the upper end of which is reduced in both interior and exterior diameter, the upper edge of this tubular extension being provided with slots 18, which lie in the lines of diameters of the tubular extension.

Upon the outer face of the tubular extension 17 and below the reduced upper end portion thereof1 is formed a circumscribing flange 19, which acts as a support for a gallery 2O and also for the uprights 21 of the mantlesupport,` the lower ends of these uprights being engaged in perforations in the flange and having their upper ends connected by the cross-bar 22, from which the mantle 23 is hung.

The upper end of the tubular extension 17 is what may be termed the burner-head,

and when the burner is used in connection with artificial a screen 21H5 engaged in the upper end of this burner-head.

In the manufacture of this burner the body, togetherwith thetubularextensions,is formed integral, the nipple being screwed into the lower end of the body, as above described, so that its upper or discharge end will be at its proper height, after which it is clamped by means of a set-screw. The device is then screwed onto the arm of the bracket or chandelier and the damper is adjusted to secure the proper air-feed, it being understood that air enters not only through the damper-openings but through the openings 16 in the bottom of the body and also through the slots 1S lin the upper edge of the burner-head.

It will be understood that in practice modifications of the specific constructions shown may be made, and any suitable materials and proportions may be used for the Various parts without departing from the spirit of the invention.

It will be notedupon reference to Fig. 2 of the drawings that the burner head is increased in interior diameter from a point some distance below the upper end of the head to a point near to the upper end of the head, and above this portion of increased diameter the interior of the burner is reduced in diameter below the diameter of the bottom portion of the head. With this construction the mixture of gas and air expands in the portion of maximum diameter, and which portion may be termed the expansion-chamber, and in its subsequent passage through the portion of minimum diameter it moves with a greater velocity than would be the case if the head were of constant diameter, so that the mantle is better filled with the mixture of gas and air.

What is claimed is- A burner of the class described comprising a globular body portion having air and gas inlets, a burner-head, and a tubular neck connecting the head and body portion, the bore of the discharge end of the head being the same as that of the neck and the bore of the head directly adjacent to the neck being abruptly expanded to maximum cylindrical diameter and then tapered curvingly to the diameter of the upper end ofthe head for the purpose set forth.

In testimony whereof we afiix our signatures in presence of two witnesses.
